yes, you can plug in two, you'll end up with two /dev/ttyACM* devices - the 
default onerng.sh script will not handle this particularly well - if your goal 
is to compare two devices you're best to uninstall this software anyway (as 
it's going to suck data out of one of the devices).

The  /dev/ttyACM* devices will look like serial devices - to compare them put 
them into raw mode, send them commands to turn them on and grab the bitstreams 
that result
